CHAIR.

Application filed March 15, 1924.

T (4% whom it may concern:

Be it knownthat I, FRANK M. NAYsMrrH, a citizen of the United States,residing at Kansas City, in the county of Jackson and State of Missouri,have invented certain new and useful Improvements in Chairs; and I dodeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to whichappertains to make and use the same, reference being had to theaccompanying drawings, and to the figures of reference marked thereon,which form a part of this specification.

This invention relates to chairs and pertioularly to a reclining chair,the purpose of the invention being to provide a chair which can beadjusted for either a. sitting position or a reclining position withoutthe necessity of utilizing pawls, ratchets, racks, pinions or otheroperating mechanism. The chair is so constructed that it will have acertain poise or balance, adapting it to swing with the natural swing ofthe occupant so that the occupant may shift his or her position in anatural way, accomodating itself to the change of position.

The novel construction of the invent-ion will be apparent by referenceto the following description in connection with the ac companyingdrawings, in which Fig. 1 is an end elevational view of a chairconstructed in accordance with my invention.

Fig. 2 is a front elevational view of the same.

Fig. 3 same.

Fig. 4 is a vertical. longitudinal sectional view through the chair.

Fig. 5 is a detailed fragmentary view through the foot rest and itsconnecting means, and

Fig. 6 is a detailed perspective view of one of the back brace bars, theseat rail and part of one of the rear legs showing the stop for the backbrace bar supporting rod which also supports the rear of the seat rails.

There are four legs'l, 2, 3, and 4. The legs are pivoted as at 5, thelegs 1 and 3 being complementary rear and front legs on one side and thelegs 2 and 4 being com plementary rear and front legs for the oppositeside. These legs are properly spaced by rounds or rods 6 and 7 The rearlegs is a rear elevational view of the Serial No. 699,451.

preferably carry castors 8 and similar cas tors 9 are provided for thefront legs. The seat 10 is supported upon the seat frame consisting ofthe two side bars or rails 11 and 12. The front portions of the rails 11and 12 are supported upon the upper ends of the legs 1 and 2 by'rivets13. The rear of the frame is supported on the pivots 14 and 14 whichextend through the lower ends of the two side bars 15 and 16 of the back17.

The back is supported by the back bracing side bars 18 and 19 which arepivoted to the bars 15 and '16 by rivets20. The lower ends of the bracebars 18 and 19 are loosely mounted upon a transverse rod 21 whichextends entirely across the chair and which is removably supported uponthe baci: legs by the hook shaped stops or rests 22 and Mounted on therod 21 are two links 24 and 25., each of which is provided with anelongated slot 26 through which a transverse rod 27 carried by the frontlegs 3 and 4v extends. The upper ends of the front legs 3 and 4 areconnected to the transverse rod 27 on the seat by links 23 and 29, sothat when the back 17 is raised or lowered to swing the seaton 13, thefront legs 2 and 4 will also swing.

A leg rest 30 consisting of two side bars 31 and 32 are pivoted to thetwo side arms 33 and 34 at 35, the side arms being supported by thepivots 20. The two side bars 31 and 32 are supported on the rivets 13and they preferably carry a leg supporting plate 36 intermediate theirends and at their lower ends there is a transverse connecting rod 37.The inner ends of the leg rest sup porting bar are links 38 and 39 towhich are secured foot rest supporting bars 40 and 4l carrying a footrest. The foot rest is best shown in Fig. 5' It is illustrated asconsisting of a metallic pipe or tube 42 which is received in recess 43in the members 40 and 41, the members 40 and 41 being held tight againstthe ends of the tube 42 by a bolt 44 which runs entirely through thetube. The tube is preferably covered by some soft material such asrubber to provide a resilient covering 45. The rod 37 may also besubstantially the same construction as that shown in Fig. 5, that is itmay be made up of a tube, with a rubber covering and fastened by a boltsimilar to the bolt 44. The upper face of the seat is preferably curvedas indicated at 46 to conform to the anatomy of the occupant and theback is preferably curved inward as at t? for the same reason.

The several elements of the chair structure are so arranged andbalanced, one with respect to the other that the occupant of the chairmay sit upright or lean back without liability of the chair becomingover-bah anced as is liable to happen with those chairs which dependsimply upon locking devices for holding the parts in position. When theoccupant leans backward to tilt the back 17 in a rearward direction, thelower ends of the side bars 15 and 16 push the side bars 11 and 12forward which carry the seat 10 and at the same time the lower ends ofthe side hars 15 and 16 of the back 17 shift the arm rests 33 and 3rearward to tilt the leg rest and foot rest upwardly to conform to therequirements of the pedal extremities of the body. Each part balances orcounter-balances by properly adjusted parts so that the chair may beshifted to any proper angle of inclination by simply bending forward orbackward while the occupant is in the chair and while I have found sucha chair particularly applicable for use as an invalid chair, itadmirably serves as a rest chair and it can be used as a reading orsewing chair, merely by having the occupant to lean forward enough tocause the back to approach a vertical position in which position theback part of the seat 10 will be slightly lowered.

From the foregoing, it will be apparent that the chair may be used as areclining chair with the seat and back adjusted to any angle at theoption of the occupant and that this adjustment is due to the poise orbalance of the movable parts, therefore the adjustnirents can be madethrough the action of the body of the occupant so that the chair willaccommodate itself automatically to the shifting position of theoccupant and it is also important that the chair can be folded so thatit will occupy a relatively small space for storage, shipment or thelike.

hat I claim and desire to secure by Letters-Patent is 1. A recliningchair comprising front legs and rear legs, the front legs being pivotedto the rear legs intermediate their ends, a

seat frame pivoted to the front ends of the rear legs, a back pivoted tothe rear end of the seat frame, back supporting braces pivoted at theirupper ends to the back, a rod to which the braces are connected, seatson the rear legs for receiving the rod, links carried by the rod andhaving slotted portions, a rod connecting the front legs and extendingthrough the slotted portions of the links and connections between theupper ends of the front legs and intermediate portions of the seatframe.

2. A. reclining chair con'iprising front legs and rear legs, the frontlegs being pivoted to the rear legs intermediate their ends, a seatframe pivoted to the front ends of the rear legs, a back pivoted to therear end of the seat frame, back supporting braces pivoted at theirupper ends to the back, a rod to which the braces are connected, seatson the rear legs for receiving the rod, links carried by the rod andhaving slotted portions, a rod connecting the front legs and extendin gthrough the slotted portions of the links and connections between theupper ends of the front legs and intermediate portions of the seatframe, a leg rest pivoted to the front of the seat frame and arm membershaving loose connections with the upper ends of the leg rests and withthe back.

3. A reclining chair comprising front legs and rear legs, the front legsbeing pivoted to the rear legs intermediate their ends, a seat framepivoted to the front ends of the rear legs, a back pivoted to the rearend of the seat frame, back supporting braces pivoted at their upperends to the back, a rod to which the braces are connected, seats on therear legs for receiving the rod, links carried by the rod and havingslotted portions, a rod connecting the front legs and extending throughthe slotted portions of the links and connections between the upper endsof the front legs and intermediate portions of the seat frame, a legrest pivoted to the front of the seat frame and arm memhers having looseconnections with the up per ends of the leg rests and with the back, anda pivoted foot rest carried by the lower end of the leg rest.

In testimony whereof I affix my signature.
